i just downloaded ana 1.5 synth today. i a not sure how to install. i a using ableton live 8. windows 7 64 bit. please walk through 
just run the installer and select you vst plugins folder when it asks you.br
br
normally:br
br
program files/steinberg/vstpluginsbr
br
orbr
br
program files/vstpluginsbr
br
or br
you can put it anywhere and use the option of selecting ableton custom vst plugin folder in ableton preferences.
i did that but when i go to the vst folder the 2 files there are:br
A.n.a.dllbr
a.n.ax64.dllbr
br
but i cant click on any
you dont need to click them they should just show up in ableton.
